~4 Tbps per fiber / link( 40 Gbps x 100 waves )
Optical SW Bandwidth
OPXC Path: 4T bps x 256 port
= 1.0PPacket: 4T bps x 128
port= 0.5P
DWDM Bandwidth
◇IX Traffic: 100 Gbps→100 Tbps◇Access: 10 Mbps→10 Gbps◇Backbone Node : Tbps→Pbps
◇IX Traffic: 100 Gbps→100 Tbps◇Access: 10 Mbps→10 Gbps◇Backbone Node : Tbps→Pbps
Year 2015 Traffic at Backbone
